A discussion of chemical hot and cold packs can really warm up a classroom lesson on thermochemistry. In this hands-on activity, students use a coffee cup calorimeter to measure the heat of solution of a chemical salt using 3 different masses and then design their own hot and/or cold pack.
Matter is the substance of which all material is made. That means objects which have mass. Energy is used in science to describe how much potential a physical system has to change. In physics, energy is a property of matter. It can be transferred between objects, and converted in form. It cannot be created or destroyed.
